NAME ORIGIN

Suggested by the Rev. Allen Wright, chief of the Choctaws, to designate
his tribal land, once commonly known as the Indian Territory (1866). From Choctaw
okla "people" and humma or homma "red," thus "land of
the red people." The name was orginally applied to a railroad station that
became Oklahoma City, then was used for the Territory of Oklahoma in 1890,
and hence the state.
